摘要：
Method for winding a fibre element (2) onto a support (16), said fibre element comprising at least two longitudinal portions (P i ) with different characteristics, comprising the steps of supplying the fibre element to the support and associating with each longitudinal portion a respective value of the winding pitch (p i ) which is different from the values associated with the portions adjacent thereto; the winding pitch associated with each portion being optionally modulated in accordance with a periodic function.
A device for carrying out the above method is also disclosed.
Also a method for distinguishing the different longitudinal portions of the fibre product produced by the above method is disclosed, comprising the steps of unwinding the fibre and detecting the variations in winding pitch. An apparatus for carrying out the latter method is also disclosed.
